Rock cheeks

Used to describe the act of having sex. Most commonly used in reference to hitting it from behind. Literally, having sex with butt cheeks.

Dude #1 : Hey bro, did you end up hooking up last night ?
Dude #2 : Oh yeah man. I took home a dime and I rocked those cheeks all night.

Dude #1 : Are you hanging out tonight ?
Dude #2 : No man, your sister is coming over tonight and she wants to rock cheeks.
Dude #1 : oh cool, wait, what the fuck ?

uruguayan rock

The act of telling absurd stories in a completely serious way, with the goal of testing how far one can go with it until people call out their bullshit.

"Dude, my friend and I were at this party where we would go around telling people we met whilst catching fish barehanded on a lake in Wallonia. I shit you not, half the girls actually believed it and wanted to bang us right then and there."

"Man, that's Uruguayan rock at its best."
